Description

Technical Field

[0001] This application relates to the field of environmental protection machinery, and particularly to a solid-liquid mixture treatment device. Background Art

[0002] During industrial production and processing, a large amount of solid-liquid mixtures are generated, such as sewage, cleaning waste liquid, etc. And in these solid-liquid mixtures, there are a large number of insoluble solids, and some of the solids can be recycled. If the solid-liquid mixture is directly discharged, it will cause waste of resources and harm to the environment. Therefore, it is necessary to separate these solids from the solid-liquid mixture for subsequent purification treatment.

[0003] In related technologies, the action of natural precipitation is usually used to remove the solids in the solid-liquid mixture. However, this precipitation method requires the solid-liquid mixture to stay in the sedimentation device for a long time, resulting in a low treatment efficiency of the sedimentation device for the solid-liquid mixture. Summary of the Invention

[0004] Aiming at the above deficiencies in the prior art, the present invention provides a solid-liquid mixture treatment device, which can improve the treatment efficiency of the solid-liquid mixture.

[0005] To solve the above technical problems, the present invention provides a solid-liquid mixture treatment device, including:

[0006] A sedimentation tank, in which a honeycomb flow guide member is arranged. The honeycomb flow guide member is respectively communicated with the inlet and outlet of the sedimentation tank, so that the solid-liquid mixture entering the sedimentation tank through the inlet of the sedimentation tank is conveyed to the outlet of the sedimentation tank through the honeycomb flow guide member;

[0007] A first filtration tank, the inlet of the first filtration tank is communicated with the outlet of the sedimentation tank. A guide member is arranged in the first filtration tank, and the guide member is used to divide the first filtration tank into a first space and a second space. The first space is connected to the inlet of the first filtration tank, and the second space is connected to the outlet of the first filtration tank. The guide member is provided with a filtration port and a flow-through port, so that a part of the solid-liquid mixture entering the first space through the inlet of the first filtration tank enters the second space through the filtration port, and another part enters the second space through the flow-through port. And the included angle between the opening direction of the filtration port and the opening direction of the flow-through port is 30° to 90°.

[0008] In the present application, since a honeycomb flow guide member is provided in the sedimentation tank, and both ends of the honeycomb flow guide member are respectively communicated with the inlet and the outlet of the sedimentation tank, thus, the solid-liquid mixture entering the sedimentation tank through the inlet of the sedimentation tank will first pass through the honeycomb flow guide member and then flow to the outlet of the sedimentation tank. In addition, as is well known, the diameter of the honeycomb tubes in the honeycomb flow guide member is relatively small. Compared with the inlet of the sedimentation tank, the diameter of the honeycomb tubes in the honeycomb flow guide member is much smaller than the inlet of the sedimentation tank. Therefore, when the solid-liquid mixture entering the sedimentation tank through the inlet of the sedimentation tank passes through the honeycomb flow guide member, the honeycomb flow guide member can reduce the flow rate of the solid-liquid mixture, thereby facilitating the precipitation of the solids in the solid-liquid mixture.

[0009] Moreover, since the inlet of the first filtration tank is communicated with the outlet of the sedimentation tank, thus, after the honeycomb flow guide member accelerates the precipitation of the solids in the solid-liquid mixture in the sedimentation tank, the solid-liquid mixture will enter the first filtration tank. Since a guiding member is provided in the first filtration tank, and the guiding member divides the first filtration tank into a first space connected to the inlet of the first filtration tank and a second space connected to the outlet of the first filtration tank, and the guiding member is also provided with a filtration port and a flow-through port, therefore, the solid-liquid mixture entering the first space through the inlet of the first filtration tank will respectively enter the second space through the filtration port and the flow-through port. Through the guiding of the guiding member, the flow rate of the solid-liquid mixture entering through the first filtration tank can be reduced, thereby improving the precipitation effect of the solids in the solid-liquid mixture in the first space.

[0010] In addition, since the included angle between the opening direction of the filtration port and the opening direction of the flow-through port is 30° to 90°, therefore, the opening direction of the filtration port and the opening direction of the flow-through port are not parallel. Then, the flow directions of the solid-liquid mixture entering the second space through the filtration port and the flow-through port are different. When the liquid flows of the two solid-liquid mixtures entering the second space through the filtration port and the flow-through port converge, a vortex will be formed at the convergence of the liquid flows of the two solid-liquid mixtures passing through the filtration port and the flow-through port, thereby achieving the purpose of reducing the flow rate of the solid-liquid mixture in the second space, being beneficial to the precipitation of the solids in the solid-liquid mixture in the second space, improving the precipitation effect of the solids in the solid-liquid mixture, and thus improving the precipitation efficiency of the solid-liquid mixture treatment device for the solids in the solid-liquid mixture.

[0011] In a possible implementation manner, the filtration port is arranged close to the outlet of the first filtration tank, and the flow-through port is arranged far from the outlet of the first filtration tank;

[0012] The outlet of the sedimentation tank is arranged close to the filtration port.

[0013] Since the outlet of the sedimentation tank is arranged close to the filtration port, the filtration port is arranged close to the outlet of the first filtration tank, and the overflow port is arranged far from the outlet of the first filtration tank. Therefore, on the one hand, the flow path of the solid-liquid mixture passing through the overflow port is extended, thereby prolonging the residence time of the solid-liquid mixture in the first filtration tank. On the other hand, the speed of the solid-liquid mixture passing through the overflow port is slowed down, which is more conducive to forming a vortex at the confluence of the two solid-liquid mixtures passing through the filtration port and the overflow port, improving the sedimentation effect of the solids in the solid-liquid mixture in the second space.

[0014] In a possible implementation manner, the inlet area of the first filtration tank is s1, and the outlet area of the first filtration tank is s2, where s2≥2s1.

[0015] When the outlet area of the first filtration tank is greater than or equal to twice the inlet area of the first filtration tank, it means that the outlet area of the first filtration tank is relatively large compared to the inlet area of the first filtration tank, which can improve the deceleration of the solid-liquid mixture at the outlet of the first filtration tank, and thus improve the sedimentation effect of the solids in the solid-liquid mixture in the first filtration tank.

[0016] In a possible implementation manner, the solid-liquid mixture treatment device further includes a second filtration tank. The inlet of the second filtration tank is connected to the outlet of the first filtration tank. A first filter screen is arranged in the second filtration tank. The first filter screen is used to divide the second filtration tank into a first filtration space and a second filtration space. The first filtration space is connected to the inlet of the second filtration tank, and the second filtration space is connected to the outlet of the second filtration tank.

[0017] Thus, by providing a second filtration tank connected to the first filtration tank and a first filter screen arranged in the second filtration tank, it can ensure that the liquid passing through the outlet of the second filtration tank first passes through the filtration of the first filter screen, thereby guaranteeing the sedimentation effect of the solid-liquid mixture treatment device on the solids in the solid-liquid mixture.

[0018] In a possible implementation manner, a second filter screen is arranged on the filtration port, and the mesh holes of the second filter screen are smaller than the mesh holes of the first filter screen.

[0019] Since the second filter screen on the filtration port can filter more solid-liquid mixture and prevent solids from entering the second space, by making the mesh holes of the second filter screen smaller than those of the first filter screen, it can increase the flow rate of the solid-liquid mixture passing through the first filter screen when filtering the solid-liquid mixture entering the second filtration tank, thereby improving the sedimentation efficiency of the solid-liquid mixture treatment device on the solids in the solid-liquid mixture.

[0020] In a possible implementation manner, the honeycomb tubes in the honeycomb flow guide member are inclined from the inlet of the sedimentation tank to the outlet of the sedimentation tank, and in the height direction of the sedimentation tank, the end of the honeycomb tube close to the inlet of the sedimentation tank is lower than the end close to the outlet of the sedimentation tank.

[0021] Since the honeycomb tubes in the honeycomb flow guide member are inclined from the inlet of the sedimentation tank to the outlet of the sedimentation tank, thus, in the height direction of the sedimentation tank, the flow path of the solid-liquid mixture is extended. Also, because in the height direction of the sedimentation tank, the end of the honeycomb tube close to the inlet of the sedimentation tank is lower than the end close to the outlet of the sedimentation tank, therefore, the solid-liquid mixture entering the sedimentation tank can flow from the bottom of the sedimentation tank to the top of the sedimentation tank, thereby further reducing the speed of the solid-liquid mixture passing through the honeycomb flow guide member, and further improving the sedimentation effect of the sedimentation tank on the solids in the solid-liquid mixture.

[0022] In a possible implementation manner, the included angle between the honeycomb tube and the height direction of the sedimentation tank is between 25° and 65°.

[0023] By setting the included angle between the honeycomb tube and the height direction of the sedimentation tank to be between 25° and 65°, it can not only ensure the deceleration effect of the honeycomb tube on the solid-liquid mixture, but also improve the sedimentation effect of the honeycomb tube on the solids.

[0024] In a possible implementation manner, a flow guide assembly is further arranged in the sedimentation tank. The flow guide assembly is located at the bottom of the sedimentation tank, and a flow guide channel is arranged on the flow guide assembly. The flow guide channel can lead the solids deposited on the honeycomb flow guide member to the sedimentation tank.

[0025] Thus, by arranging the flow guide assembly, the solids deposited at the bottom of the sedimentation tank can be timely led to the sedimentation tank to avoid affecting the subsequent solid-liquid separation treatment of the solid-liquid mixture.

[0026] In a possible implementation manner, the flow guide assembly includes a rotating shaft, guide vanes, a driving machine and a power pump. The rotating shaft is arranged at the bottom of the sedimentation tank and is located below the honeycomb flow guide member. The guide vanes are spirally arranged on the rotating shaft to form the flow guide channel. The driving machine is connected to the rotating shaft to drive the rotating shaft to rotate. The power pump is used to suck the high-concentration solid-liquid mixture guided by the flow guide channel.

[0027] Since the rotating shaft is arranged at the bottom of the sedimentation tank and is located below the honeycomb guide piece, the guide blades are spirally arranged on the rotating shaft to form a guide channel. Therefore, the deceleration of the solid-liquid mixture by the honeycomb guide piece can accelerate the precipitation of solids in the solid-liquid mixture. The precipitated solids will fall into the guide channel. When the driving machine drives the rotating shaft to rotate, the solids can move along the guide channel formed by the guide blades to one end of the rotating shaft, and finally be pumped out by the power pump, thereby removing the precipitated solids from the sedimentation tank. The structure is simple and can avoid the accumulation of more sediment in the sedimentation tank, thereby ensuring the sustainability of the sedimentation tank.

[0028] In a possible implementation, an inclined guide plate is further provided between the bottom of the sedimentation tank and the honeycomb guide member, and the inclined guide plate is used to guide the precipitated fixed objects toward the guide channel.

[0029] Therefore, by setting an inclined guide plate, the precipitated solids can be guided to the guide channel, so that the precipitated solids can be prevented from being dispersed at other positions on the bottom of the sedimentation tank, which is beneficial to reducing the precipitated solids in the sedimentation tank. At the same time, it can also prevent the precipitated solids from occupying the space in the sedimentation tank, thereby improving the sedimentation effect of the sedimentation tank on the solids in the solid-liquid mixture and the processing efficiency of the solid-liquid mixture.

[0030] In a possible implementation, the sedimentation tank includes a first sedimentation tank and a second sedimentation tank connected to each other, and the second sedimentation tank is also connected to the first filter tank;

[0031] The honeycomb flow guide member includes a first honeycomb flow guide member and a second honeycomb flow guide member. The first honeycomb flow guide member is disposed in the first sedimentation tank, and the second honeycomb flow guide member is disposed in the second sedimentation tank.

[0032] Since the sedimentation tank includes a first sedimentation tank and a second sedimentation tank, and a first honeycomb guide member is arranged in the first sedimentation tank and a second honeycomb guide member is arranged in the second sedimentation tank, the sedimentation effect of the sedimentation tank on solids in the solid-liquid mixture is improved, and the density of solids in the solid-liquid mixture entering the first filter tank is reduced.

[0033] In a possible implementation, a second preset angle is formed between the extension directions of the honeycomb tubes in the first honeycomb flow guide member and the honeycomb tubes in the second honeycomb flow guide member.

[0034] By making the extension directions of the honeycomb tubes in the first honeycomb flow guide and the honeycomb tubes in the second honeycomb flow guide have a second preset included angle, on the one hand, it can make the flow direction of the solid-liquid mixture in the first sedimentation tank different from that in the second sedimentation tank, thereby further reducing the flow rate of the solid-liquid mixture and improving the sedimentation effect of the sedimentation tank on the solids in the solid-liquid mixture. On the other hand, it can make the first filtration tank be arranged on the same side of the first sedimentation tank and the second sedimentation tank, improving the structural compactness of the solid-liquid mixture treatment device.

[0035] In a possible implementation manner, a spoiler is arranged at the inlet of the second sedimentation tank.

[0036] By arranging a spoiler at the inlet of the second sedimentation tank, the flow direction of the solid-liquid mixture entering the second sedimentation tank can be changed, thereby initially decelerating the solid-liquid mixture entering the second sedimentation tank. On the one hand, the impact of the solid-liquid mixture on the second honeycomb flow guide is reduced, and the service life of the second honeycomb flow guide is improved. On the other hand, the sedimentation effect of the second sedimentation tank on the solids in the solid-liquid mixture is improved. Description of the Drawings

[0051] As described in the background art of the present application, in the related art, the solid matter in the solid-liquid mixture is usually removed by the action of natural sedimentation. However, this sedimentation method requires the solid-liquid mixture to stay in the sedimentation device for a long time, resulting in low processing efficiency of the sedimentation device for the solid-liquid mixture.

[0052] To solve the technical problems mentioned in the background art, the present invention provides a solid-liquid mixture treatment device. By arranging a honeycomb flow guide member in the sedimentation tank, the flow rate of the solid-liquid mixture passing through the honeycomb flow guide member can be reduced, which is beneficial to the separation of the solid matter in the solid-liquid mixture from the solid-liquid mixture. And by arranging a guide member in the first filtration tank and providing filter openings and overflow openings with an included angle of 30° to 90° in the opening direction on the guide member, the solid-liquid mixture in the first space can be divided into two liquid flow mixtures with different directions, and the liquid flows converge to the second space, and vortices are formed at the confluence of the two solid-liquid mixtures, so as to achieve the purpose of slowing down the flow rate of the solid-liquid mixture, improving the sedimentation effect of the solid matter in the solid-liquid mixture, and further improving the processing efficiency of the solid-liquid mixture.

[0053] The following will detail the present application through specific embodiments:

[0054] See Figure 1 , Figure 2 and Figure 3, an embodiment of the present application provides a solid-liquid mixture treatment device 100. The device includes a sedimentation tank 110 and a first filtration tank 120. Among them, a honeycomb flow guide member 111 is arranged in the sedimentation tank 110. The honeycomb flow guide member 111 is respectively communicated with the inlet and the outlet of the sedimentation tank 110, so that the solid-liquid mixture entering the sedimentation tank 110 through the inlet of the sedimentation tank 110 is conveyed to the outlet of the sedimentation tank 110 through the honeycomb flow guide member 111; the inlet of the first filtration tank 120 is communicated with the outlet of the sedimentation tank 110. A guide member 121 is arranged in the first filtration tank 120. The guide member 121 is used to divide the first filtration tank 120 into a first space 120a and a second space 120b. The first space 120a is connected to the inlet of the first filtration tank 120, and the second space 120b is connected to the outlet of the first filtration tank 120. A filtration port 1211 and a flow-through port 1212 are arranged on the guide member 121, so that a part of the solid-liquid mixture entering the first space 120a through the inlet of the first filtration tank 120 enters the second space 120b through the filtration port 1211, and another part enters the second space 120b through the flow-through port 1212, and the included angle between the opening direction of the filtration port 1211 and the opening direction of the flow-through port 1212 is 30° to 90°.

[0055] Among them, the above-mentioned honeycomb flow guide member 111 includes a plurality of honeycomb tubes arranged in an array. The plurality of honeycomb tubes are parallel and the tube walls of adjacent honeycomb tubes are closely attached or shared. In this way, the solid-liquid mixture entering from the inlet of the sedimentation tank 110 can be conveyed to the outlet of the sedimentation tank 110 through the honeycomb flow guide member 111.

[0056] The above-mentioned guide member 121 can be a tubular structure or a plate-like structure. In this embodiment, the plate-like structure is mainly taken as an example for illustration. Exemplarily, the guide member 121 is a guide plate. One end of the guide plate is hermetically connected to the inner wall of the first filtration tank 120 and is located between the outlet of the sedimentation tank 110 and the inlet of the first filtration tank 120. The other end of the guide plate extends in a direction away from the outlet of the first filtration tank 120.

[0057] In addition, the opening direction of the above-mentioned filtration port 1211 refers to the direction indicated by the Y arrow, and the opening direction of the flow-through port 1212 refers to the direction indicated by the X arrow. The range of the included angle between the opening direction of the filtration port 1211 and the opening direction of the flow-through port 1212 is not strictly limited. The included angle between the opening direction of the filtration port 1211 and the opening direction of the flow-through port 1212 includes but is not limited to 30° to 90°.

[0058] In this embodiment, since a honeycomb flow guide member 111 is provided in the sedimentation tank 110, and both ends of the honeycomb flow guide member 111 are respectively communicated with the inlet and the outlet of the sedimentation tank 110, thus, the solid-liquid mixture entering the sedimentation tank 110 through the inlet of the sedimentation tank 110 will first pass through the honeycomb flow guide member 111 and then flow to the outlet of the sedimentation tank 110. In addition, as is well known, the diameter of the honeycomb tubes in the honeycomb flow guide member 111 is relatively small. Compared with the inlet of the sedimentation tank 110, the diameter of the honeycomb tubes in the honeycomb flow guide member 111 is much smaller than the inlet of the sedimentation tank 110. Therefore, when the solid-liquid mixture entering the sedimentation tank 110 through the inlet of the sedimentation tank 110 passes through the honeycomb flow guide member 111, the honeycomb flow guide member 111 can reduce the flow rate of the solid-liquid mixture, thereby facilitating the precipitation of the solids in the solid-liquid mixture.

[0059] Moreover, since the inlet of the first filtration tank 120 is communicated with the outlet of the sedimentation tank 110, therefore, the solid-liquid mixture after the honeycomb flow guide member 111 accelerates the precipitation of the solids in the solid-liquid mixture in the sedimentation tank 110 will enter the first filtration tank 120. Since a guide member 121 is provided in the first filtration tank 120, and the guide member 121 divides the first filtration tank 120 into a first space 120a connected to the inlet of the first filtration tank 120 and a second space 120b connected to the outlet of the first filtration tank 120, and the guide member 121 is further provided with a filtration port 1211 and a flow-through port 1212, thus, the solid-liquid mixture entering the first space 120a through the inlet of the first filtration tank 120 will enter the second space 120b through the filtration port 1211 and the flow-through port 1212 respectively. Through the guidance of the guide member 121, the flow direction of the solid-liquid mixture entering the first space 120a can be changed, thereby reducing the flow rate of the solid-liquid mixture entering through the first filtration tank 120, and further improving the precipitation effect of the solids in the solid-liquid mixture in the first space 120a.

[0060] In addition, since the included angle between the opening direction of the filtration port 1211 and the opening direction of the flow-through port 1212 is 30° to 90°, therefore, the opening direction of the filtration port 1211 and the opening direction of the flow-through port 1212 are not parallel. Then, the flow directions of the solid-liquid mixture entering the second space 120b through the filtration port 1211 and the flow-through port 1212 are different (see Figure 2The liquid flow direction shown by the dashed arrow in the figure), when the liquid flows of the two solid-liquid mixtures entering the second space 120b through the filtering port 1211 and the liquid passing port 1212 converge, an eddy current will be formed at the convergence of the liquid flows of the two solid-liquid mixtures passing through the filtering port 1211 and the liquid passing port 1212, so as to achieve the purpose of reducing the flow rate of the solid-liquid mixture in the second space 120b, which is beneficial to the precipitation of the solids in the solid-liquid mixture in the second space 120b, improving the precipitation effect of the solids in the solid-liquid mixture, and thus improving the precipitation efficiency of the solid-liquid mixture treatment device 100 for the solids in the solid-liquid mixture.

[0061] In some possible embodiments, referring to Figure 3 , the filtering port 1211 is arranged near the outlet of the first filtering tank 120, and the liquid passing port 1212 is arranged away from the outlet of the first filtering tank 120; the outlet of the precipitation tank 110 is arranged near the filtering port 1211.

[0062] In this embodiment, since the outlet of the precipitation tank 110 is arranged near the filtering port 1211, the filtering port 1211 is arranged near the outlet of the first filtering tank 120, and the liquid passing port 1212 is arranged away from the outlet of the first filtering tank 120, therefore, on the one hand, the flow path of the solid-liquid mixture passing through the liquid passing port 1212 is extended, so as to extend the residence time of the solid-liquid mixture in the first filtering tank 120, improving the precipitation effect of the solids in the solid-liquid mixture, and on the other hand, the speed of the solid-liquid mixture passing through the liquid passing port 1212 is slowed down, so as to be more conducive to the formation of an eddy current at the convergence of the two solid-liquid mixtures passing through the filtering port 1211 and the liquid passing port 1212, improving the precipitation effect of the solids in the solid-liquid mixture in the second space 120b.

[0063] In some possible embodiments, the inlet area of the first filtering tank 120 is s1, and the outlet area of the first filtering tank 120 is s2, and s2≥2s1.

[0064] If the outlet area of the first filtering tank 120 is less than twice the inlet area of the first filtering tank 120, it means that the outlet area of the first filtering tank 120 is small, and the inlet area of the first filtering tank 120 is large, or the inlet area and the outlet area of the first filtering tank 120 are approximately equal. Then, the deceleration effect of the outlet of the first filtering tank 120 on the solid-liquid mixture in the first filtering tank 120 is not obvious, which is not conducive to the first filtering tank 120 improving the precipitation effect of the solids in the solid-liquid mixture. On the contrary, when the outlet area of the first filtering tank 120 is greater than or equal to twice the inlet area of the first filtering tank 120, it means that the outlet area of the first filtering tank 120 is larger compared with the inlet area of the first filtering tank 120, so as to improve the deceleration of the outlet of the first filtering tank 120 on the solid-liquid mixture, and further improve the precipitation effect of the solids in the solid-liquid mixture in the first filtering tank 120.

[0065] In some possible embodiments, refer to Figure 2 and Figure 4 , the solid-liquid mixture processing device 100 further includes a second filter tank 130. The inlet of the second filter tank 130 is connected to the outlet of the first filter tank 120. A first filter screen 130a is arranged in the second filter tank 130. The first filter screen 130a is used to divide the second filter tank 130 into a first filter space 131 and a second filter space 132. The first filter space 131 is connected to the inlet of the second filter tank 130, and the second filter space 132 is connected to the outlet of the second filter tank 130.

[0066] Thus, by providing the second filter tank 130 connected to the first filter tank 120 and arranging the first filter screen 130a in the second filter tank 130, it can be ensured that the liquid passing through the outlet of the second filter tank 130 first passes through the filtration of the first filter screen 130a, thereby ensuring the precipitation effect of the solid-liquid mixture processing device 100 on the solids in the solid-liquid mixture.

[0067] In some possible embodiments, refer to Figure 3 and Figure 4 , a second filter screen 12111 is arranged on the filter port 1211. The mesh holes of the second filter screen 12111 are smaller than those of the first filter screen 130a.

[0068] Since the second filter screen 12111 on the filter port 1211 can filter more solid-liquid mixture and prevent solids from entering the second space 120b, by making the mesh holes of the second filter screen 12111 smaller than those of the first filter screen 130a, it is possible to increase the flow rate through the first filter screen 130a when filtering the solid-liquid mixture entering the second filter tank 130, thereby improving the precipitation efficiency of the solid-liquid mixture processing device 100 on the solids in the solid-liquid mixture.

[0069] In some possible embodiments, refer to Figure 5 , the honeycomb tubes in the honeycomb flow guide member 111 are inclined from the inlet of the sedimentation tank 110 towards the outlet of the sedimentation tank 110, and in the height direction of the sedimentation tank 110, the end of the honeycomb tube close to the inlet of the sedimentation tank 110 is lower than the end close to the outlet of the sedimentation tank 110.

[0070] Wherein, the height direction of the sedimentation tank 110 refers to Figure 5 the direction indicated by the Z arrow in

[0071] Since the honeycomb tube in the honeycomb guide member 111 is inclined from the inlet of the sedimentation tank 110 to the outlet of the sedimentation tank 110, the flow path of the solid-liquid mixture is extended in the height direction of the sedimentation tank 110. In addition, because in the height direction of the sedimentation tank 110, the end of the honeycomb tube close to the inlet of the sedimentation tank 110 is lower than the end close to the outlet of the sedimentation tank 110, the solid-liquid mixture entering the sedimentation tank 110 can flow from the bottom of the sedimentation tank 110 to the top of the sedimentation tank 110, thereby further reducing the speed of the solid-liquid mixture passing through the honeycomb guide member 111, thereby improving the sedimentation effect of the sedimentation tank 110 on the solid matter in the solid-liquid mixture.

[0072] In addition, the honeycomb guide member 111 can be in a block shape or in a plate shape. For example, when the honeycomb guide member 111 is in a plate shape, for the installation of the plate-shaped honeycomb guide member 111, the area of ​​the honeycomb guide member 111 of a corresponding size can be designed according to the size of the sedimentation tank 110. Specifically, the area size of the honeycomb guide member 111 can be designed according to L1 / v=L2 / u, and Q=nvdB, wherein L1 is the length of the inclined surface of the honeycomb guide member 111, and L2 is the length of the honeycomb guide member 111 in the sedimentation tank 110. The thickness in the height direction, v is the flow velocity of the solid-liquid mixture in the honeycomb tube of the honeycomb guide member 111, u is the rising velocity of the solid-liquid mixture in the honeycomb tube of the honeycomb guide member 111 along the height direction of the sedimentation tank 110, Q is the total flow rate passing through the honeycomb guide member 111, n is the number of columns of multiple honeycomb tubes along the inclined direction of the honeycomb tube, d is the tube diameter of the honeycomb tube, B is the width of the honeycomb guide member 111, and B=md, m is the number of rows of multiple honeycomb tubes along the width direction of the honeycomb guide member 111.

[0073] In some possible embodiments, the angle between the honeycomb tube and the height direction of the precipitation tank 110 is between 25° and 65° (i.e. Figure 5 The angle α shown in the figure).

[0074] If the angle between the honeycomb tube and the sedimentation tank 110 in the height direction is too small, it means that the angle between the honeycomb tube and the horizontal direction is large, which means that the honeycomb tube is close to vertical, thereby shortening the flow path of the solid-liquid mixture in the honeycomb tube. If the angle between the honeycomb tube and the sedimentation tank 110 in the height direction is too large, it means that the angle between the honeycomb tube and the horizontal direction is small, which means that the honeycomb tube is close to horizontal, which is not conducive to the falling of precipitated solids, thereby causing blockage of the honeycomb tube and affecting the precipitation of solids in the solid-liquid mixture. Based on this, the angle between the honeycomb tube and the sedimentation tank 110 in the height direction is between 25° and 65°, which can not only ensure the deceleration effect of the honeycomb tube on the solid-liquid mixture, but also improve the precipitation effect of the honeycomb tube on the solids.

[0075] Exemplarily, the included angle between the honeycomb tube and the height direction of the sedimentation tank 110 can be 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, etc., but is not limited to the above-exemplified angles.

[0076] In some possible embodiments, referring to Figure 5 , a flow guiding assembly 140 is further disposed in the sedimentation tank 110. The flow guiding assembly 140 is located at the bottom of the sedimentation tank 110, and a flow guiding channel 140a is provided on the flow guiding assembly 140. The flow guiding channel 140a can export the solids precipitated on the honeycomb flow guiding member 111 to the sedimentation tank 110.

[0077] Thus, by providing the flow guiding assembly 140, the solids deposited at the bottom of the sedimentation tank 110 can be timely exported to the sedimentation tank 110, so as to avoid affecting the subsequent solid-liquid separation treatment of the solid-liquid mixture.

[0078] In some possible embodiments, referring to Figure 6 , the flow guiding assembly 140 includes a rotating shaft 141, guiding vanes 142, a driving machine 143 and a power pump 144. The rotating shaft 141 is disposed at the bottom of the sedimentation tank 110 and is located below the honeycomb flow guiding member 111. The guiding vanes 142 are spirally arranged on the rotating shaft 141 to form the flow guiding channel 140a. The driving machine 143 is connected to the rotating shaft 141 to drive the rotating shaft 141 to rotate. The power pump 144 is used to suck the high-concentration solid-liquid mixture guided by the flow guiding channel 140a.

[0079] Since the rotating shaft 141 is disposed at the bottom of the sedimentation tank 110 and is located below the honeycomb flow guiding member 111, and the guiding vanes 142 are spirally arranged on the rotating shaft 141 to form the flow guiding channel 140a, therefore, after the honeycomb flow guiding member 111 decelerates the solid-liquid mixture, it can accelerate the precipitation of the solids in the solid-liquid mixture. The precipitated solids will fall into the flow guiding channel 140a. When the driving machine 143 drives the rotating shaft 141 to rotate, the solids can move along the flow guiding channel 140a formed by the guiding vanes 142 to one end of the rotating shaft 141, and finally be pumped out by the power pump 144, thereby removing the precipitated solids from the sedimentation tank 110. The structure is simple, and it can also avoid the accumulation of more precipitates in the sedimentation tank 110, ensuring the sustainability of the operation of the sedimentation tank 110.

[0080] In addition, the driving machine 143 can be a driving machine 143 such as a rotating motor, a motor and a speed reducer in the prior art that can realize the rotation of the rotating shaft 141. Since the guiding vanes 142 are spirally arranged on the rotating shaft 141, the flow guiding channel formed by the guiding vanes 142 arranged on the rotating shaft 141 is a spiral flow guiding channel, and the blades are relatively thin, and the width of the formed flow guiding channel is relatively large.

[0081] In addition, the power pump 144 includes, but is not limited to, a submersible pump, a suction pump, etc. Since a large amount of precipitated solids will accumulate at the bottom of the sedimentation tank 110, when the rotating shaft 141 rotates to guide the fixed objects through the spiral diversion channel, the density of the solids in the solid-liquid mixture in the diversion channel is much greater than the density of the solids in the solid-liquid mixture in the honeycomb guide member 121. Therefore, the solid-liquid mixture guided by the diversion channel 140a is a high-density solid-liquid mixture.

[0082] In some possible embodiments, referring to Figure 6 , an inclined guide plate 112 is further provided between the bottom of the sedimentation tank 110 and the honeycomb diversion member 111. The inclined guide plate 112 is used to guide the dropped fixed objects to the diversion channel 140a.

[0083] Thus, by providing the inclined guide plate 112, the dropped solids can be guided to the diversion channel 140a. In this way, the precipitated solids can be prevented from dispersing to other positions at the bottom of the sedimentation tank 110, which is beneficial to reducing the precipitated solids in the sedimentation tank 110. At the same time, it can also prevent the precipitated solids from occupying the space in the sedimentation tank 110, improving the sedimentation effect of the solids in the solid-liquid mixture in the sedimentation tank 110 and the treatment efficiency of the solid-liquid mixture.

[0084] Optionally, there are two inclined guide plates 112, and the two inclined guide plates 112 are oppositely arranged on opposite sides of the rotating shaft 141 to increase the guiding area of the inclined guide plate 112.

[0085] Optionally, the bottom of the sedimentation tank 110 is arc-shaped, and the arc shape matches the outer circumference of the guide vane 142. In this way, the guiding effect of the diversion channel 140a on the fixed objects can be improved.

[0086] In some possible embodiments, referring to Figure 5 and Figure 6 , the sedimentation tank 110 includes a first sedimentation tank 110a and a second sedimentation tank 110b connected to each other, and the second sedimentation tank 110b is also connected to the first filtration tank 120; the honeycomb diversion member 111 includes a first honeycomb diversion member 1111 and a second honeycomb diversion member 1112. The first honeycomb diversion member 1111 is arranged in the first sedimentation tank 110a, and the second honeycomb diversion member 1112 is arranged in the second sedimentation tank 110b.

[0087] Since the sedimentation tank 110 includes the first sedimentation tank 110a and the second sedimentation tank 110b, and the first honeycomb diversion member 1111 is arranged in the first sedimentation tank 110a and the second honeycomb diversion member 1112 is arranged in the second sedimentation tank 110b, the sedimentation effect of the sedimentation tank 110 on the solids in the solid-liquid mixture is improved, and the density of the solids in the solid-liquid mixture entering the first filtration tank 120 is reduced.

[0088] Optionally, a guiding inclined plate 113 is disposed at an extension of the inlet of the first sedimentation tank 110a. The guiding inclined plate 113 is connected to the inclined guiding plate 112, and the inclination direction of the guiding inclined plate 113 is the same as that of the inclined guiding plate 112, so as to initially decelerate the solid-liquid mixture when the solid-liquid mixture enters the first sedimentation tank 110a, and improve the sedimentation effect of the first sedimentation tank 110a on the solids in the solid-liquid mixture.

[0089] In some possible embodiments, there is a second preset included angle between the extending directions of the honeycomb tubes in the first honeycomb flow guiding member 1111 and the honeycomb tubes in the second honeycomb flow guiding member 1112.

[0090] By making there be a second preset included angle between the extending directions of the honeycomb tubes in the first honeycomb flow guiding member 1111 and the honeycomb tubes in the second honeycomb flow guiding member 1112, on the one hand, it can make the flowing direction of the solid-liquid mixture in the first sedimentation tank 110a different from the flowing direction of the solid-liquid mixture in the second sedimentation tank 110b, thereby further reducing the flowing speed of the solid-liquid mixture and improving the sedimentation effect of the sedimentation tank 110 on the solids in the solid-liquid mixture. On the other hand, it can make the first filtration tank 120 be disposed on the same side of the first sedimentation tank 110a and the second sedimentation tank 110b, improving the structural compactness of the solid-liquid mixture treatment device 100.

[0091] In some possible embodiments, referring to Figure 6 , a spoiler plate 114 is disposed at the inlet of the second sedimentation tank 110b.

[0092] By disposing the spoiler plate 114 at the inlet of the second sedimentation tank 110b, the flowing direction of the solid-liquid mixture entering the second sedimentation tank 110b can be changed, thereby initially decelerating the solid-liquid mixture entering the second sedimentation tank 110b. On the one hand, the impact of the solid-liquid mixture on the second honeycomb flow guiding member 1112 is reduced, and the service life of the second honeycomb flow guiding member 1112 is improved. On the other hand, the sedimentation effect of the second sedimentation tank 110b on the solids in the solid-liquid mixture is improved.

[0093] Optionally, the spoiler plate 114 is disposed on the inner wall of the inlet of the second sedimentation tank 110b, and there is an included angle between the spoiler plate 114 and the inner wall of the inlet of the second sedimentation tank 110b, and this included angle can be but not limited to 30°, 35°, 40°, 45°, 50°, 55°, 60°, etc.

[0094] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
